Abstract: The synthesis of novel N-isopropyl-O-aryl-O'-galactopyranosyl thiophosphoramidates was reported, and the conditions of the reactions were discussed.Apure isomer of N-isopropyl-O-(p-chlorophenyl)-O'-galactopyranosyl thiophosphoramidate 3d, 3d' , was obtained by recrystallization from diethyl ether-petroleum ether. The result of X-ray diffraction analysis showed that the configuration of the chiral phosphorus atom of 3d' was of R-form.The herbicidal and antidisease activities of the title compounds were tested.

Key words: Thiophosphoramidate, Galactopyranosyl, Herbicidal activity, Antidisease activity
